To all whom it may concern Be it known that l, Huisnr citizen of the United States, residing in the l borough ot Brooltlyn, county o Kings, State of lllevv York, have invent@ a new and useful lllasherless llla-nce@ ot which the following is a specilication.v Y.

The object ofI my presen invention is to ,devise a novel construction of a faucet 0r valve wherein l* am enabled to dispense Wit the necessity .oit employing a was-her in order to maintaineJ iiuidtiglat seal between the valve audits seat.

With the alcove and other koloj ects in. view, lt Which Will hereinatterfmore fully appear in the detailed description, mydnvention con siste ort a novel construction and arrangement of a .washerlesstaucet,

lt further consists of a novel construction of a valve seat, a novel construction oit valve coperating therewith and: novel means ior il@ regulatingthe*position or" said valve.,

Fig. 2 represents a sectional view similar to llig. 1, but showing the valve and its adjuncts in the position they assume when the valve is in closed and locked position. valve-7 to move away from the seat 1S and Fig. 3 represents a section on line new?, permitthe fluid to pass trom the inlet 5 to Fi 1. l th-ooi-1tlet11.

BROWN, a l

14 with the casing memloer 15 designates an actuating handle secured to the valve spindle 13. The forward end of the valve spindle 13 is pre-ierally rounded and in proximity to such end the spindle is slotted as is indicated at 16.

1n order to secure the valve 'l in operative condition with 'respect to the valve l'spindle 13, l provide a pin 17 which passes thro-ugh the valve 7, and through the recess 9 therein, and also through the slot 1G lin the valve spindle 13. rl`he innerface of ythe casing member- 2 surrounding the vpassage 1Q, forms a valve seat 18, and is preferably rounded as shown in the drawing.

ln the operation of my invention, assum ing that the parts are in the position seen in liig. 2. it will be seen that the valve 7 is locked in closed position, since the pin 17 isseated at the outer ond of ,the slot 16. When the spindle 13 is moved inwardly the iii-ner rend thereof contacts with the rear Wall of the recess 9, thereby causing the tension 4thereby adapting the same to be is a rotary movement, which action is couconnected with any desired source of fluid tinued until the back of the` slot 1 6 engages su ply, which enters the valve through the the' pin 17 andcompletes the closing of the 5@ in et 5. The member 1 is provided with an valve hy drawing .the same tightly against enlarged chamber 6, with which the inlet the seat., thus locking such valve in4 closed 5 communicates, and Within this chamber 6 position. This rotary movement of the is mounted a valve of novel construction. valve while it is held against the seat only This valve 7 is'provided with an incavated -by the force of the water tends to cause the seat engaging portion 8 and is centrally refaces of both the valve and the scat to exprovides a largerand more complete cony -the injury which is vention, I have I educed'to i above description,

actly conform to each other and also rinds up the `obstacles ordinarily present' 1n the fluid. The Spherical form of the valve also tact and eliminates in a very large measure,

liable to very hard substance, and also positions the valve for the pull exerted thereagainst by the threaded spindle 13.

Special attention is directed to the fact that inmy present invention I have entirely eliminated the necessity of employing a packing or gasket in order to maintain a fluid tlght seal between the valve and its seat, and I am thereby enabled to entirely eliminate thel necessity of continuously repacking the valve at frequent intervals, such as is necessary when the ordinary types of faucets are employed.-

It will be apparent that in my present ina minimum the number of arts of the device, and since thc same may e formed of castings it will be apparent that devices, in accordance with my invention, may be very economically manufactured.

It will now be apparent -that I have devised a novel and useful construction of a washerless faucet which embodies the features of advantage enumerated as `desirable in the statementof the invention and the and while I have, in the present instance, shown and described preferred embodiments thereof which have been found in practice to give satisfactory and res liable results, it is to be understood that the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention as stated in the claims or sacrificing any of its advantages.

Having thus describedmy invention, what I claim as new and desire to secure by Letters Patent, is

l. A' valve comprising a casing having a be caused by al 1 move longitudinally of roundedseat, a spindle mounted for moveconnecting the spindle with the valve proper` whereby the said 'parts are constrained to rotate in unison with each other but may the spindle independently of each other.

2. A valve comprising a casing having a rounded seat, a spindle having a slot at one end and mounted for movement through the seat, a valve proper mounted for `pivotal movement with respect to said seat and have ing an incavated` face adapted to close against said seat and having a recess to receive the end of the spindle, and a pin secured to the valve proper and passing through said slot and capable of movement therein longitudinally of said spindle Whereby said valve and spindle rotate in unison but are capable of relative movement longitudinally of the spindle independently of each other.

3. VA valve comprising a casing having a rounded seat, a valve proper having an incavated face adapted to close against said seat and its opposite face exposed to the incoming liquid, said valve proper having a recess in its incavated face, a spindle mounted for movement through said seat and having its end adapted to abut against the rear wall of said recess to move the valve propel' away from said seat, said spindle having a slot longitudinally thereof near one end, and a pin passing through said slot and secured to said valve whereby the valve proper and stem are capable of relative pivotal and longitudinal movement but are constrained to rotate in unison.
